You’re probably tired of all the (seemingly constant) changes Facebook makes on a monthly basis, but this one’s a “biggie” — depending on how you look at it.

Chances are almost no one noticed the “radical” change at first, because it’s so minute, so microscopic, someone would have to literally zoom in to take note.

So, what has Facebook changed this time? It’s the little “Friends” icon:

But, it’s always looked like that, you say. Wrong! Before, the male silhouette appeared larger, while the lowly female silhoutte was in the rear. Now, the subtle change shows the woman taking charge. Here’s a closer look at the before-and-after:

So, whose great idea was this, and why now? We can thank Facebook’s design manager, Caitlin Winner. Explaining her decision in a post on Medium.com, Winner says she was moved to push for a change because of what the icon symbolizes:

“As a woman, educated at a women’s college, it was hard not to read into the symbolism of the current icon; the woman was quite literally in the shadow of the man, she was not in a position to lean in.”

All right, so it looks like Winner makes a fair point. Why should the male appear larger and in the forefront, right? It looks so much nicer now that they’re on even ground. Well, the woman does get a slight edge since her shoulder is in front BUT the man is slightly taller so it evens out.

That’s one small step for Facebook and one slightly larger step towards gender equality. Hooray!
